TITLE:
Opera Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA36414

VERIFY ADVISORY:
http://secunia.com/advisories/36414/

DESCRIPTION:
Some vulnerabilities and security issues have been reported in Opera,
which can be exploited by malicious people to conduct spoofing
attacks.

1) An error in the handling of intermediate certificates can result
in a revoked certificate being shown as secure.

2) An error related to the collapsed address bar can result in the
previous domain being shown in the address bar instead of the domain
of the present site.

3) An error in the handling of certain unicode characters in the
address bar can be exploited to conduct limited spoofing attacks via
International Domain Names (IDN).

4) An error in the handling of certificates, which use a wild card
immediately before the top level domain, or nulls in the domain name
can be exploited to bypass validation checks and incorrectly present
a certificate as secure.

SOLUTION:
Upgrade to version 10.0.

PROVIDED AND/OR DISCOVERED BY:
3) The vendor credits Chris Weber of Casaba Security.
4) The vendor credits Dan Kaminsky.
